Restore the Ctrl + Alt + Num Pad 4 and 6 window positioning commands?
I got used to using Ctrl+Alt+Numpad to move windows around in Ubuntu 11.04. Since I updated to Ubuntu 12.04, however, numpad shortcuts 4, 6, and 0 don't work. Those are the most important ones!
Is there another set of shortcut keys for these operations, or is there a way to bring them back?
